Definitions
- the present invention concerns a disposable capsule for beverages; the capsule containing powder or ground products intended for the preparation of beverages such as coffee, tea or the like in dispensing machines.
- EP 1440910 concerns a disposable capsule for the preparation of beverages starting from a food product containing liquid or powder milk, or containing roasted or ground coffee, tea, etc..
- the disposable capsules available for the preparation of beverages are obtained from plastic materials, such as polyolefins (e.g. polypropylene and polyethylene and/or copolymers thereof) or laminated films of polyolefins and aluminium suitable for use in the food field.
- US 4646626 discloses capsules from a plastic material provided with one or more holes, obtained on the lid, to allow the inflow of pressurized water during their use. The beverage exits the capsule through an opening in the bottom and an underlying collector. Because of the holes, in order to avoid the oxidation and the deterioration of the organoleptic characteristics of the product, capsules are distributed in sealed packages, as for example the so called "blisters".
- the capsule is hermetically packaged between a pre-formed tray from a plastic material and a foil made from plastic or aluminium. The latter must be removed to allow its use in the dispensing machine.
- disposable capsules are known intended to be perforated at the time of their use.
- perforation of the capsule when it is used is operated by one or more lances, or piercing elements, which penetrate the capsule from the outside to the inside. Breaking of the container walls, or their perforation, may cause the release of particles of the same capsule that fall inside the container, mixing with the food product. As a consequence, the dispensed beverage may also be disagreeable and have a poorly appetizing aspect, or worst, may contain extraneous parts.
- US 5656316 (Nestec ) concerns a disposable capsule for beverages whose upper wall can be perforated by a conduct for feeding of pressurized water inside the capsule.
- means for the capsule opening are provided on the beverage dispensing machine, having the disadvantage of contacting the beverage, with resulting cross-contamination problems when capsules for different beverages are utilized.
- a further example of a system for opening the capsule through mobile lances or piercing elements is the one related to the capsule described in the international patent application WO2004/026091 (Kraft )
- EP 1344722 discloses a cartridge comprising at least a disc shaped fluid director member, acting also as a filter, and an auxiliary frame member, which separates the fluid director member from the bottom of the cartridge, which is pierced by a piercing member.
- EP 1344724 discloses a beverage cartridge a including a filter dividing the cartridge in an upper brewing chamber and a beverage receiving chamber, having a recess to support the filter during brewing.
- capsules have another drawback.
- the amount of product to be housed inside the capsule depends on the type of the beverage to supply.
- capsules used for soluble beverages generally contain up to about 20 grams soluble powder
- the capsules used for dispensing coffee generally contain up to about 10 grams of powder coffee. Consequently, the volume of the capsule has to be adapted, during the design, to the different uses which the capsule is intended for.
- the capsules for the soluble beverages have greater dimensions than the corresponding dimensions of the capsules for coffee, for example the height of the capsule for soluble beverages may be greater than the height of the capsules for coffee.
- the machines provided for dispensing the beverages have to be designed in such a way to be compatible with the different available capsules.
- capsules having sizes standardized as much as possible It is required to provide capsules, having a given size, which can be utilized for the soluble beverages and for the coffee indifferently, or more generally, to provide capsules which can be utilized indifferently for dispensing beverages also in the case that the amount of the dose to be encapsulated differs between the various cases.
- a further object of the present invention is to provide a disposable capsule which is suitable to be sealed in a controlled atmosphere, or vacuum-packed, without using further capsule packages for preserving the organoleptic properties of the beverage.
- Another object of the present invention is to provide a capsule for the preparation of different beverages (or other similar foodstuff), compatible with automatic or hand-loaded dispensing machines, which allows for the encapsulation of different product doses in its inside, each dose with the suitable compactness grade depending on the kind of beverage to be dispensed, with no need for changing the external dimensions of the capsule.
- the disposable capsule according to the present invention for the preparation of a beverage from a food product housed therein, which capsule comprises a plurality of walls and means for dispensing the beverage, characterized in that it comprises at least an element for the partition of the internal volume of the capsule in two or more volumes for housing at least said food product, said partition element being fixed with respect to the capsule.
- the volumes of the capsule may contain one or more food products, each in its optimal configuration, for example coffee powder with the right grounding grade and with the suitable compression.
- the partition element is housed internally to the capsule, for example secured or snap-engaged, preferably in correspondence of its lower portion.
- the partition element is a disc or a substantially cylindrical spacer intended to support the food product between its upper wall and the upper wall of the capsule.
- the disc - or the spacer - works as a double bottom for the capsule.
- the upper wall of the spacer is in fluid communication with the lower wall of the capsule (for example it is bored), in order to have the beverage prepared with the food product housed in the upper volume of the capsule to flow into the lower volume and then trough the opening for dispensing the beverage.
- the upper wall of the spacer is provided with a filter in order to block the solid portion of the beverage during its distribution.
- the partition element may be snap-coupled to the lower portion of the capsule or it can be welded to the same. It is important that it reduces and/or divides the internal volume of the capsule without modifying the functioning thereof, thus permitting the normal beverage supply.
- the capsule provided with the partition element contains different products for a beverage into different volumes or chambers defined by the partition element inside the capsule.
- coffee may be housed in the upper chamber and powder (or liquid) milk into the lower chamber.
- the capsule of the invention is particularly advantageous since it can be used indifferently for the preparation of soluble beverages or for the preparation of coffee from ground powder.
- the capsule is not provided with the spacer and the internal volume of the capsule is the maximum.
- the spacer is inserted into the capsule before this is filled with the coffee powder, and the internal volume of the capsule is thus divided in a lower volume and in an upper volume, for example the upper volume is reduced of the amount necessary to house a lower dose of food product, maintaining at the same time the desired compactness grade.
- the same capsule having fixed outer size, i.e. without requiring two different capsules to be provided, having different sizes, each of which is for the preparation of a beverage of one type.
- the beverage prepared from the capsule may be more or less diluted also depending on how compacted is the encapsulated product.
- the partition element according to the invention thus allows to adjust such compactness grade in order to dispense more or less diluted beverages, as for example required In different States.
- the partition element has predefined dimensions, i.e. it is calibrated to provide the partition of the capsule volume depending on the quality and the amount of the beverage requested by the user according to his taste.
- the volume dividing element, or partition element should be resistant to the pressure exerted by the water and the food product during the preparation of the beverage, without being subject to deformations which might cause an undesired bypass of solid product to the outside of the same element and the filter, along the capsule walls.
- the partition element is preferably designed to have a structure optimized to support the different pressures which generate in the capsule depending on the different amounts and groundings of the contained product and on the different supplying pressure of the water. In fact different dispensing pressures are often provided in various countries, as well as different product amounts, which product also has its predefined particle size.
- the spacer may be designed to resist to pressures in the range from 1,5 bar to 20 bar, more frequently from 3 bar to15 bar, so to allow a filter element (coupled to the same spacer or provided into it) to operate without being deformed.
- the means for perforating the capsule operate the perforation of the film when this deforms under the force of an external pressure, for example the pressure exerted by the pressurized hot water directed toward the capsule, and its film, for the beverage preparation.
- the means for perforating the film are provided on the capsule wall, preferably the upper wall, which is located adjacent and underlying the film which seals the capsule.
- the means for the perforation of the film are fixed and bonded with respect to the capsule and, for instance, comprise one or more cutting projections.
- the cutting projections may be integral with a surface of the capsule and may have different shapes. For example they may be sharp cusps or wedges, and also they may have a generally pyramidal shape.
- the film is externally provided and covers the whole upper wall of the capsule, so to hermetically seal it, and the cutting projections are cusps located on the upper surface of the same wall, directed toward the film.
- the cusps are preferably located in correspondence of through holes provided in the upper wall of the capsule to supply pressurized water inside the capsule, where the food product, e.g coffee powder, is housed.
- the capsule according to the invention has numerous advantages over prior art.
- the film which seals the capsule of the invention is perforable at the time of the actual use of the capsule by perforation means which are fixed to the capsule.
- the film has not to be manually separated from the capsule before its use and has not to be perforated by means provided on the machines loaded with the capsule (as in the capsule according to US 5656316 ).
- the capsule according to the invention is thus simple to pack and to use, and also guarantees high quality standards for the contained foodstuff which keeps unaltered for a long time, in an optimal conservation state, the organoleptic characteristics.
- the capsule according to the present invention has a simplified structure, because the surfaces for the perforation of the film are fixed, and permits to perfectly isolate the food product from the external environment, while resulting inexpensive.
- the capsule of the invention is particularly suitable for the use with machines for the preparation of coffee or beverages.
- the film of the capsule can be moved toward the cutting projections by the pressurized water supplied by such machines for dispensing the beverages.
- the film breaks only when the capsule is actually used, allowing the water to enter the capsule itself.
- Figure 1 shows a capsule C according to the invention, comprising a container 1, an upper wall 2 suitable to close the container 1 and a film 4.
- the upper wall 2 together with the film 4 hermetically close the assembled capsule C.
- the wall 2 may be welded to the container 1 through ultrasound welding.
- the film 4 is fixed, for example is thermo-welded, to the container 1 coupled to the wall 2, for example by thermo-welding the film 4 on a peripheral circular area of the wall 2.
- the capsule C may contain different food products 3.
- the capsule C of figures 1 and 2-2C is suitable for the preparation of beverages from fresh ground products, e.g. coffee or the like, while the capsule shown in the figures 3A-3C can be used for the preparation of beverages from soluble products.
- the encapsulated product is coffee powder 3, compressed in the container 1 to a predefined compactness grade, known in the art.
- the film 4 is coupled to the upper wall 2, in order to seal it from the external atmosphere.
- the upper wall 2 is provided with a plurality of holes 5 which set in fluid communication the upper surface of the same wall 2 with the internal volume of the container 1, and thus with the coffee powder.
- holes 5 allow the pressurized water supplied by the pump to enter the assembled capsule upon it has passed through the film 4.
- the task of the latter is to seal the capsule C until it is used, preventing the product 3 from being exposed to the air through the holes 5 of the wall 2, thus deteriorating or loosing its characteristics.
- the number and the arrangement of the cusps 6 may vary depending on the needs. In the case shown in the figures 1-2C , the cusps 6 are eighteen, arranged in two concentric circular series ( figure 2A ). However, the cusps 6 may be a different number and may provide different arrangements, star like, triangle like, asterisk like, etc.
- the cusps 6 have a star-like shaped cross section, with a triangular shaped contour in vertical section. This shape has proved particularly effective since the film 4, perforated by the cusps 6 with circular holes, does not adhere to the external surface of the cusp 6, and passages remain between the film 4 and the cusps 6, sufficient to allow the water flow to penetrate under the film 4.
- the cusps 6 may be obtained with other shapes, different from the shown one. For instance, the cusps 6 may have a jigsaw tooth shape, and thus may tilt with respect to direction D, with a pyramidal shape, etc..
- the film 4 can be a traditional type one, for example a film utilized in the food field for sealing packages.
- film 4 must have good mechanical characteristics in order to resist to undesired ruptures, but at the same time it must be sufficiently flexible in order to be deformed by a fluid flow which impinges on it.
- the film has to be rapidly and easily perforable when contact with the cusps 6 starts.
- the film 4 is of a multilayer type, made of a plurality of coupled films, among which an aluminum film and one or more plastic films may be provided, possibly reporting the manufacturer's data and/or the data concerning the product 3.
- Figure 4 shows a capsule C assembled and ready to be used in beverage dispensing machine.
- the opening of the capsule C in correspondence of its upper portion is operated by the water flow supplied by the machine on the film 4.
- the water flows between the film 4 and the surface 7 and through holes 5 into capsule C, where the coffee powder is.
- the opening of the lower portion 8 is achieved through the rupture of the frangible mobile element or trap 9 operated by a piercing element (or collector) of the same machine or by the increasing of the internal pressure in the capsule C due to the water entering the same.
- the trap 9 has the square shape shown in the figures 1 and 4 .
- the shape delineated by the breaking lines 10 - which define the trap 9 - is generally square or "window” like (with two wings), that is the trap may be torn in two halves which open as a wing.
- the portion of the piercing element intended to break the trap 9 preferably has a circular section, as schematically shown in figure 10, with a diameter having length lower than, or equal to, the side 10 of the trap 9. During the perforation of the trap 9, this configuration provides gaps 12 which permit the coffee to flow outside from the capsule C.
- the figures 3A-3C show the upper wall 20 of a capsule C according to the present invention, designed for soluble beverages.
- capsules used for the preparation of soluble beverages (chocolate, tea, white coffee, etc.) contain a greater amount of product 3 than the correspondent capsules for the coffee (for example up to 20 grams of soluble powder versus about 8 grams of ground coffee).
- the number and the arrangement of the holes 25 and cusps 26 are different with respect to the correspondent holes 5 and cusps 6 of the wall 2.
- the position of the holes 25 on the wall 20 is as much as possible peripheral in order to supply the water to the encapsulated product 3 in its entirety.
- Two cusps 26 are provided in correspondence of the holes 25 for perforating the film 4.
- Figures 5-6D show a capsule C provided with a partition element having the function of dividing, or partitioning, its internal volume.
- the partition element may have different shapes and dimensions depending on the specific uses which the capsule C is intended to.
- the partition element is constituted by a spacer 40 having a predefined height extension, in such a way that once inserted in the container 1, the internal volume of the container left available to the product 3 is reduced to the room 62 included between the upper surface 41 of the spacer 40 and the upper surface 7 of the capsule C.
- the spacer 40 allows the capsule C to be used both for the preparation of the coffee and for the preparation of soluble beverages.
- the capsule C is coupled to the spacer 40
- the capsule C has no spacer 40 and the internal volume of the container 1 may be completely filled with the product 3.
- spacer 40 may be inserted in the container 1 at the time of the filling of the capsule C with the product 3. If the amount of product 3 is for example not greater than 10 grams, the spacer 40 is inserted in the container 1 and works as a double bottom for the capsule C. If the product is soluble, the container 1 does not contain the spacer.
- the element for dividing the volume of the capsule may be provided also in the traditional capsules, i.e. independently by the provided means for the opening of the capsule.
- the spacer 40 permits to encapsulate the product 3 according to the most opportune load and/or the compactness grade.
- the reduction of the convenient volume of the capsule C may be designed to obtain the desired compactness grade for the product 3 in the capsule C.
- the figures 1 and 5 show a capsule C provided with a spacer 40 and with opening means of the above mentioned type.
- a paper filter or another approved material for foodstuff, is interposed between the spacer 40 and the product 3, in order to stop any powder 3 which has not solubilized during the preparation of the related beverage.
- Another filter may be interposed between the product 3 and the upper wall of the capsule C.
- the spacer 40 is provided with a set of holes 42 in correspondence of the wall 41.
- the element for partitioning/reducing the volume of the capsule may have the shape of the spacer 40 which - as shown has a cylindrical shape, is substantially hollow and abuts the bottom of the capsule.
- such partitioning element may have the shape of a disk or a septum (52 or 54) and may stand on a base 51 provided on the capsule wall.
- other shapes are possible. It is sufficient that the partition element 40, 52 or 54 is fixed to container 1, for example by way of a fit coupling or welding, and allows the passage of the beverage toward the trap 9.
- the capsule is preferably provided with the trap 9, having two halves which open by departing one from the other.
- the "double wing" like opening of the trap 9 minimizes the risks that interferences generate between the two halves of the trap 9 (the wings) pushed by the piercing element inside the capsule C and the element 40, 52, 54 provided within the capsule C.
- a single wing trap 9 once it has been opened, may contact the lower wall of the spacer or disk, thus interfering with the proper beverage dispensing, for example preventing part of the foam formed by the infusion of the product 3 inside the capsule to exit.
- the trap 9 has a square or quadrilateral shape in combination with a circular shape of the section of the piercing element 50A, in order to obtain a plurality of gaps for the beverage exit in correspondence of the trap vertices. In this way the presence of foam is increased in the dispensed product.
- the capsule C according to the present invention may be provided with an opening sealed by a film which is perforable by the piercing element.
- a film which is perforable by the piercing element is provided on the bottom of the container 1 and sealed is a film perforable by the piercer-collector 50 or by an equivalent element.
- the spacer 40 is provided with a supporting surface 45 suitable to contact the piercing element 50A.
- the supporting surface for example a rise or a shim, permits the piercing element 50A to abut the spacer, and to support the same during the beverage dispensing and avoiding harmful "swellings", i.e. deformations toward the capsule C bottom due to the force exerted by the internal pressure during the dispensing of the beverage.
- the support provided by the piercing element 50A of the collector 50 improves the resistance of the capsule C to the deformations caused by the increase of the internal pressure, which deformations may cause the passage of powder around the capsule filter.
- the thickness of the supporting surface 45 may be greater or smaller depending on the distance between the disk 52 or 54 and the capsule bottom, in such a way that the surface 45 is always substantially abutting the piercing element 50A: for example, in the figures 6A and 6B the thickness of the supporting surface 45 is greater than the one of the embodiment of figures 6C and 6D because the volume defined upwardly from the partition element is lower than the one of figures 6C and 6D .
- a volume 60 is provided between the lower wall of each element 40, 52 or 54 and the bottom 8 of the container 1.
- the volume 60 may be used for housing food product, for example a second product which, together the product 3, is used to prepare the beverage.
- the volume 60 may be completely or partially filled with powder milk, or with liquid milk, powder cocoa, etc..
- the elements 40, 52 or 54 for dividing/reducing the volume of the capsule C may thus be designed also for maximizing or minimizing the volume 60.
- the element 54 of figure 6D may be provided with a lower portion 61 having a toroidal shape.
- the capsules according to the present invention may be madeof known common plastic materials used in this field, for example polyolefins (e.g. polypropylene and polyethylene and/or copolymers thereof), or multilayer polyolefin and aluminium suitable for use in the food field, according to the needs of each particular application.
- polyolefins e.g. polypropylene and polyethylene and/or copolymers thereof
- multilayer polyolefin and aluminium suitable for use in the food field, according to the needs of each particular application.
